Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to wastewater treatment equipment and method for polyaluminium chloride production. Background Art

[0002] Polyaluminium chloride is usually prepared by reacting calcium aluminate ore powder with hydrochloric acid; the production process mainly includes steps such as dissolution, aging, precipitation and drying, among which the wastewater from the dissolution process may contain impurities such as iron and silicon, the aging wastewater may contain high molecular polymers, and the washing wastewater may contain suspended matter and small particles of solids.

[0003] In the patent document with application number 202411116616.5, applicant Shandong Lvran Environmental Protection Technology Co., Ltd., and subject name A wastewater treatment device and method for polyaluminium chloride production, the wastewater treatment device provided includes a quantity adjustment feeding part, a staggered movable unit, and an alternating liquid discharge part; wherein, through the alternating liquid discharge part, when the spur gear ring rotates, the U-shaped connecting frame will be driven to rotate, so that the adapter shaft drives the liquid accumulation bucket to rotate relative to the baffle plate, at this time, when the first liquid discharge pipe discharges the agent and the second liquid discharge pipe discharges the wastewater, as the liquid accumulation bucket rotates, the wastewater and the agent can be alternately dropped into the cavity between the partition and the liquid accumulation bucket, so as to achieve full mixing of the wastewater and the agent; however, in actual use, the alternating liquid discharge part has the following problems: First, the reagents discharged from the first liquid discharge pipe and the wastewater discharged from the second liquid discharge pipe are discharged into the cavity between the partition and the liquid accumulation bucket in sequence. Although the reagents and wastewater can produce a certain mixing effect through solution diffusion during the rotation of the liquid accumulation bucket, there is a problem of uneven mixing; Secondly, after the reagent is added into the wastewater, it will produce flocculent floating matter, sediment and other substances, especially sedimentary substances. When they settle directly to the bottom of the liquid accumulation bucket, it is easy to cause blockage to the first diversion hole and the second diversion hole, affecting the normal operation of the equipment.
